Noise reduction water nozzle

Abstract

The invention discloses a noise reduction water nozzle, and belongs to the field of water utilization pipe fittings. The noise reduction water nozzle can eliminate impact noise. The noise reduction water nozzle comprises a handle and a water outlet pipe, wherein the water outlet pipe is connected with a spiral pipe which rotates in a cylindrical spiral shape outwards; the axial direction of the spiral pipe is not vertical but horizontal; the inner diameter of the spiral pipe is larger than the inner diameter of the water outlet pipe; the tail end of the spiral pipe is connected with a downward drainage pipe; and the entire height position of a pipe cavity cross section at the highest part of the spiral pipe is higher than the height position of a pipe cavity cross section at the highest part of the water outlet pipe. The noise reduction water nozzle is applicable to water nozzle devices of water supply terminals.

Description

technical field [0001] The invention relates to a water supply pipe fitting, in particular to a sound-absorbing faucet. Background technique [0002] As a water supply terminal, the faucet is inseparable in people's daily life. It is generally composed of several parts such as a water inlet pipe, a valve body, a handle, and a water outlet pipe. The water inlet pipe is connected to the water supply pipeline. The water flows directly downward through the outlet pipe with the opening facing downward. Due to the wide distribution of end users and the uneven height and location, in order to ensure and meet the needs of normal water use at various terminals, the water supply in the main water supply line and branch line piping system The pressure must maintain a high pressure value, such a pressure will bring a problem to the user at a lower position: the water flow rate of the faucet is high, and the impact force of the water flowing out of the faucet outlet is very strong when...

[0002] As a water supply terminal, the faucet is inseparable in people's daily life. It is generally composed of several parts such as a water inlet pipe, a valve body, a handle, and a water outlet pipe. The water inlet pipe is connected to the water supply pipeline. The water flows directly downward through the outlet pipe with the opening facing downward. Due to the wide distribution of end users and uneven heights, in order to ensure and meet the needs of normal water use at various terminals, the water supply in the main water supply line and branch line piping system The pressure must maintain a high pressure value, such a pressure will bring a problem to the user at a lower position: the water flow rate of the faucet is high, and the impact force of the water flowing out of the faucet outlet is very strong when the water is released. Loud, producing loud noises, sometimes up to 60-70 decibels according to measurements, such noises will undoubtedly affect or even interfere with other people in the same room. Modern life requires quietness in all aspects. Elimination or reduction of treatment is urgently needed by people, so it is necessary to improve and eliminate the problem of loud water spout.
